趋势面分析在洪山殿矿区构造和厚煤带分布研究中的应用

Application of Trend Analysis to the Study of Structure and Thickness of Coal Layer in Hongshandian Mine

通过对洪山殿矿区龙潭组Ⅳ煤层底板高程趋势面分析，认为在洪山殿矿区存在多方向的褶皱及其叠加，与本区受到多期次的构造应力场作用相吻合。而通过对Ⅳ煤层厚度趋势面分析，得出的煤层厚度在褶皱轴部加厚，翼部变薄的规律性可用来预测矿区Ⅳ煤层厚度和构造的变化。

Based on the trend analysis of bottom altitute of the fourth coal layer in Hongshandian coal mine,it is considered that there are more than one direction folds and their superposition,which is coincide with action of the structural stress fields of multi stages there.According to the trend ananlysis of thickness of the fourth coal layer there exists a regularity that the fourth coal layer increases at the axes of folds and decreases at the limbs of them.Thus author concludes that the trend analysis can be used to predict the change of thickness and structure of the fourth coal layer in Hongshandian mine.
